1. A software copyright protection and licensing system using radio-frequency identification (RFID), said system comprising:

  • a computer-readable medium embedded with a software that is to be installed and executed in a computer, wherein the software includes an installation manager;

    a RFID tag, said RFID tag contains at least a product installation and licensing key of the software; and

    a RFID reader in communication with a central processing unit (CPU) of a computer and the RFID tag;

    wherein during initial installation, when the computer-readable medium is inserted into the computer, the installation manager invokes the RFID reader which in turn interrogates the RFID tag to obtain the product installation and licensing key of the software, and requests a user to provide licensee information;

    after the software is installed, the licensee information is encrypted and sent to the RFID tag so that the product installation and licensing key is updated with the licensee information;

    then upon successful transmission of the licensee information to the RFID tag, the installation manager generates an installation signature (ISig) that is stored in the computer (ISigpc);

    the installation is deemed successful if the generation and storage of the installation signature ISig is successful; and

    wherein, during reinstallation, the installation manager obtains the ISigpc from the computer and an ISigtag from the RFID tag that is synthesized from the product installation and licensing key and the updated licensee information, and then compares the ISigpc with the ISigtag;

    if both tally, the software is reinstalled;

    if both do not tally, the software is not reinstalled.
